Unfourtunately, that is the BasicATOM, and not the BasicAtomPRO.

The speed difference is quite severe. The PRO series uses a 16 mHz  
clock.

Even using a serial DAC, I could get 4 channels to update in less  
than 1 millisecond.
I know you could not do this with the base level product.
Using a parallel DAC, you could process audio, not that you would  
want to.
